Estimator Interview Questions
Sample answer to the question
Yes, I have encountered a situation where there was a change in project scope that affected the cost estimate. In a previous construction project, we were initially tasked with building a small office building. However, midway through the project, the client requested additional rooms and amenities to be added. This change significantly impacted the cost estimate as it involved additional materials, labor, and time. To handle this situation, I immediately held a meeting with the project team to discuss the implications of the change. We reviewed the updated plans and specifications, and I recalculated the quantities and costs involved. I also reached out to suppliers and subcontractors to obtain updated quotes. With the revised information, I prepared a detailed estimate that reflected the changes and presented it to the client. I emphasized the impact of the scope change on the cost and provided clear explanations for the adjustments. Through effective communication and negotiation, we were able to reach an agreement with the client on the revised cost estimate.
A more solid answer
Certainly! I had a project where the initial scope was to construct a residential building with ten units. However, during the construction phase, the client decided to convert two of the units into a common area for the residents. This change in project scope had a direct impact on the cost estimate. To handle this situation, I followed a systematic approach. Firstly, I analyzed the revised plans and blueprints to identify the changes in materials, labor, and time required. I then consulted with my team to discuss the implications of the scope change and brainstorm potential solutions. Afterward, I conducted thorough research to gather updated pricing from suppliers and subcontractors. Utilizing my knowledge of estimating software, I recalculated the quantities and costs, ensuring accuracy and precision. Once the revised estimate was prepared, I scheduled a meeting with the client to present the changes and communicate the reasons behind the adjustments. I emphasized the importance of the common area in enhancing the overall value of the residential building. Through open dialogue and effective negotiation, we reached a mutual agreement on the updated cost estimate. This experience showcased my ability to adapt to changing project requirements, demonstrate analytical thinking, and collaborate with both internal and external stakeholders.

An exceptional answer
Absolutely! In a recent construction project, I encountered a significant change in project scope that had a profound effect on the cost estimate. We were initially contracted to build a commercial complex with four floors. However, during the early stages of construction, the client decided to add an entire floor to accommodate additional office spaces. This alteration necessitated a comprehensive reassessment of the cost estimate. To handle this substantial change, I immediately convened a project meeting to bring together key stakeholders, including architects, engineers, and subcontractors. Collaboratively, we analyzed the updated plans and specifications, meticulously examining the impact on materials, labor, and time. Leveraging my expertise in cost estimating software, I diligently recalculated the quantities and costs with utmost precision and accuracy. Furthermore, I proactively engaged in strategic discussions with suppliers and subcontractors to secure competitive quotes for the additional materials and labor required. Armed with the revised information, I formulated a detailed estimate that transparently showcased the changes and the corresponding financial implications. During a face-to-face meeting with the client, I artfully navigated the sensitive topic of cost adjustments by showcasing the value-added benefits of the additional floor space, such as increased revenue potential and enhanced market competitiveness.
